Prepare the Cheesecake Filling: Mix cream cheese, sugar, and vanilla extract in a medium bowl until smooth. Scoop portions onto a lined baking sheet and freeze for 1-2 hours.

Make the Strawberry Jam: Combine diced strawberries and sugar in a saucepan. Cook for 45 minutes, mashing halfway through until thickened. Allow to cool.

Prepare the Cookie Dough: Whisk together flour, baking powder, baking soda, and salt. Cream butter and sugar until fluffy, then mix in egg and vanilla.

Combine Mixtures: Gradually add the dry flour mixture to the wet butter mixture until just combined. Set dough aside.

Incorporate Strawberry Jam: Gently swirl the prepared strawberry jam into the dough, ensuring pockets of jam remain.

Assemble the Cookies: Flatten portions of dough, place a cheesecake disc in the center, and wrap the dough around it. Roll in sugar.

Bake the Cookies: Preheat oven to 350°F (175°C). Bake for 11-12 minutes until edges turn golden. Reshape cookies while warm for a perfect look.

Garnish & Serve: Dust cooled cookies with powdered sugar and optionally serve with fresh mint or berries.
